Mate, I do not put anything on my bottom lip, only at the last minute to help bring the scab off do I put a bit of vaseline on and that is rare. When the scab is off I leave it alone totally - no water touches it, no vasilne - nothing, I even eat things that mean I don't strech my mouth!lol like baguettes and sandwiches!. Over time I have noticed that the lip is more waxy until the scab grows over thick.When my lip is scabbing up you can now see the contours of my lip in it, like the lip is remembering what it used to be like.When I first stopped biting and left it alone it would just look like one big creator of yellow/green scab, now even though the scab gets thick it resembles my lip more.
